Answer:
The speed of space station floor is 49.49 m/s.
Explanation:
Given that,
Mass of astronaut = 56 kg
Radius = 250 m
We need to calculate the speed of space station floor
Using centripetal force and newton's second law
Where, v = speed of space station floor
r = radius
g = acceleration due to gravity
Put the value into the formula
Hence, The speed of space station floor is 49.49 m/s.
Answer:
Mass of the disk will be 2.976 kg
Explanation:
We have given force F = 45 N
Radius of the disk r = 0.12 m
Angular acceleration
We know that torque
And
So , here I is moment of inertia
So
We know that moment of inertia
So
m = 2.976 kg
Answer:
The electrons are moving through the superconductor per second.
Explanation:
Given :
Current A
Charge of electron C
Time sec
From the formula of current,
Current is the number of charges flowing per unit time.
Where number of charges means in our case number of electrons
Therefore, electrons are moving through the superconductor per second.
